Assistant Professor at the University of Wageningen, interested in atmospheric dynamics, extratropical cyclones, moisture transport and the storm tracks.
Although main findings are very similar as for winter cyclones, we did find more continental moisture sources and that there is (relatively) less exchange between primary and secondary cyclones. Moreover, we find a stronger influence of cyclones undergoing an extratropical transition.

I understand your frustration! I hope you can resubmit it, or can submit it somewhere else.

Yes, ideally you have some pressure gradient (e.g. Laplacian) or vorticity based intensity measure which should work better in both the cyclostrophic and geostrophic limit.

The pressure is also dependent on the latitude and a smaller cyclone of the same minimum pressure is much more intense as a cyclone with the same minimum pressure but twice that large.

Impact will probably/hopefully be less, also because the region of strongest winds south of #Herminia seem to pass south of Ireland.

Agreed as well, but this is the case for many diagnostics we use, like wavier or not wavier jets, influence of stratosphere interaction (there is also still debate on that: when can we really prove the stratosphere influenced the troposphere), atmospheric rivers, or my own topic cyclone clustering.

I know, but I meant also that this is mainly of interest from a scientific (and possibly modelling) point of view and probably less of interest for the general public.

I think the whole terminology is a bit confusing, if both the synoptic airflow as well possibly mesoscale sting jet play a role in forming the wind maximum, how can you separate the two? But don't know if we need another term for the combination of the two.

Which cyclone does completely follow the evolution depicted by either the Norwegian or Shapiro-Keyser model? Given its frontal evolution I would say it is clearly more a SK cyclone.
January 24, 2025 at 2:56 PM
The main issue is that the cyclone reaches maximum intensity just before it hits Ireland. Hope for the best and not too many problems.

Is this median gust from the ensemble the best predictor to your experience or would you rather go lower/higher?
January 23, 2025 at 8:48 PM
The next cyclone developing along the same jet streak is already predicted a few days later until Sunday, though it seems less intense than #Eowyn for now.

What is also interesting is quite often warm core cyclones (more like the Shapiro Keyser like evolution), which is also the case for #StormEowyn and seems to be happening again for the following cyclone as well which develops in the night till Sunday.

Choosing a default colour bar can be quite tricky, though 28 m/s might be a bit low for the extreme cases.

Dat klopt ja, ik had het eigenlijk ook vooral over Nederland (al was dat niet duidelijk in mijn vorige post). De zon is hier ook een aangename afwisseling in het grijze eind november.
